uggestion of the guide, and the further orders of their guardian,
the girls rolled in their blankets and soon were asleep. They were
awakened, shortly after twelve, by a shout from the guide. Then
followed a volley of quick shots and a warning cry from Janus Grubb.

CHAPTER XXIII

A MYSTERIOUS DISAPPEARANCE

"Quick, girls!" shouted Miss Elting.

"Thave me!" screamed Tommy Thompson.

Harriet opened her eyes in time to see Janus running rapidly from the
camp, firing his revolver at every jump. After his second shout of
warning he was not heard to speak again. For a moment or so they could
hear him crashing through the hushes, now and then firing his revolver,
probably when he caught sight of the man he was pursuing, the intruder
having no doubt returned, perhaps hoping to be able to catch the camp

expression indicated. In the meantime Miss Elting had satisfied
herself that nothing had been taken from the camp, which knowledge
served in a way to relieve her.

However, as the moments passed, and nothing further was heard from the
guide, the others of the Meadow-Brook party began to feel a vague
alarm. They could not believe that anything had happened to Janus, nor
could they understand why he should remain away from the camp so long.
Jane and Harriet "Hoo-e-e-ed!" until they were hoarse, but no reply
followed their calls. Half an hour passed; then an hou
